Elgen and Samwha radial capacitors (80's-90's) / Looking for datasheet

[thekid777]

Hello,
I'm looking for datasheet of Elgen and Samwha capacitors used at the end of the 80's.

The Elgen caps are black with a "M" on them
and Samwha are purple.
Here is some pictures

Thank you

"M" might just stand for +/-20% tolerance, so that's not a lot to go on.

Later edit: Photos might help, but... any particular reason you need the datasheets, especially since they are, by your own admission, OLD?
